A　new　type　of　electrical　storage　heater　that　utilizes　latent　heat　storage　and　flat　micro-heat　pipe　arrays　(FMHPAs)　was　developed.　The　thermal　characteristics　of　the　heater　were　tested　through　experimentation.　The　structure　and　operating　principle　of　the　storage　heater　were　expounded.　Three　rows　of　FMHPAs　were　applied　(three　rows　with　five　assemblies　each)　with　a　mass　of　28　kg　of　phase　change　material　(PCM)　in　the　heat　storage　tank.　Electric　power　was　supplied　to　the　PCM　in　the　range　of　0.2-2.04　kW,　and　air　was　used　as　heat　transfer　fluid,　with　the　volume　flow　rate　ranging　from　40-120　m(3)/h.　The　inlet　temperature　was　in　the　range　of　15-24　degrees　C.　The　effects　of　heating　power,　air　volume　flow　rate,　and　inlet　temperature　were　investigated.　The　electrical　storage　heater　exhibited　efficiencies　of　97%　and　87%　with　1.98　and　1.30　kW　of　power　during　charging　and　discharging,　respectively.　Application　of　the　proposed　storage　heater　can　transfer　electricity　from　peak　periods　to　off-peak　periods,　and　the　excess　energy　generated　by　wind　farms　can　be　stored　as　heat　and　released　when　needed.　Good　economic　and　environmental　benefits　can　be　obtained.
